Automatic power supply system capable of adjusting the power supply automatically

An automatic power supply system electrically coupled to a component to be tested, the automatic power supply system comprising:

• a power array comprising a plurality of power channels, and configured to provide power supplies through the plurality of power channels, wherein the component to be tested is electrically coupled to a first power channel of the plurality of power channels and receives a power supply through the first power channel;
• a controller electrically coupled to the power array, and configured to calculate a power of the power supply received by the component to be tested and adjust a power specification of the power supply provided through the first power channel according to the power;
• and
• a measurement module electrically coupled to the controller and the component to be tested, and configured to measure a voltage and a current received by the component to be tested, wherein the controller calculates the power of the power supply received by the component to be tested according the voltage and the current measured by the measurement module.

A method for operating an automatic power supply system, the automatic power supply system comprising a power array comprising a plurality of power channels, and a first power channel of the plurality of power channels is electrically coupled to a component to be tested, the method for operating the automatic power supply system comprising:

• providing a power supply through the first power channel to the component to be tested;
• reading a voltage value and a current value of the first power channel through the power array;
• calculating a power of the power supply received by the component to be tested according to the voltage value and the current value;
• and
• adjusting a power specification of the power supply provided through the first power channel according to the power.
